Description
上記目的を達成するため本発明の永久磁石式回転電動機は、回転子と固定子から構成され、前記固定子は、略環状の固定子鉄心と、該固定子鉄心の内周側に設けられた複数のスロット部と、前記固定子鉄心の内周側に設けられた複数のティース部と、各々のティース部にコイルを巻き回した複数の電機子巻線と、各々の電機子巻線間に配置され、両者を絶縁する樹脂製の相間絶縁シートと、を備え、該相間絶縁シートは、四箇所以上の折り目を有する断面形状を有し、内周側を幅方向に潰した状態で前記スロット部に挿入することで、内周側の前記端部の二つの折り目間の周方向距離よりも、外周側の他の二つの折り目間の周方向距離を大きくした、前記スロット部の内面に引っ掛ける拡張部を有するものとした。 In order to achieve the above object, a permanent magnet type rotary electric motor of the present invention comprises a rotor and a stator, and the stator is provided on a substantially annular stator core and an inner peripheral side of the stator core. A plurality of slot portions, a plurality of tooth portions provided on the inner peripheral side of the stator core, a plurality of armature windings in which a coil is wound around each tooth portion, and between the armature windings is disposed, and an interphase insulating sheet made of resin phases to insulate both, said phase insulating sheet has a cross sectional shape having a fold or four positions, said slot in a state of collapsed inner peripheral side in the width direction By hooking it into the slot, it is hooked on the inner surface of the slot part, where the circumferential distance between the two other folds on the outer peripheral side is larger than the circumferential distance between the two folds on the inner peripheral end. were shall we have a extension.
図３Ａは、固定子１に挿入する前の相間絶縁シート１０の斜視図である。ここに示すように、相間絶縁シート１０は、固定子１に挿入する際の組立性を向上するために、短手方向の両端部に切り欠き１２を有している。この切り欠き１２は、長手方向の一方（図３Ａでは下側）のみに配し、他方（図３Ａでは上側）は切り欠き１２を設けずに角部１３としている。なお、切り欠き１２は、短手方向両端の最外部に位置する折り目近傍まで切り欠いたものである。 FIG. 3A is a perspective view of the interphase insulating sheet 10 before being inserted into the stator 1. As shown here, the interphase insulating sheet 10, in order to improve the assembling property when inserted into the stator 1 has a notch 12 at both ends in the widthwise direction. This notch 12 is arranged only on one side in the longitudinal direction (lower side in FIG. 3A), and the other (upper side in FIG. 3A) is a corner 13 without providing the notch 12. Note that the notch 12 is notched to the vicinity of the fold located at the outermost part at both ends in the short direction.
